Abstract

Emmons discovered in 1951 that boundary layer transition occurred when some arrow shaped disturbances, or turbulent spots, formed randomly and grew as they propagated downstream until they merged and covered the entire flow field. Using Emmons’ spot hypothesis, and with a knowledge of the spot’s propagation rate and spreading angle, one could model the boundary layer intermittency distribution more accurately, hence the transition process.
